in all fairness, trying to restore an industrial battery is like trying to restore an old car, its a crapshoot on what it will take to get it back to optimal working condition. And yes as it has been said, ONLY a professional battery technition with the proper equiptment should do this.

But in my experience it should not be considered a long term investment, refurbed batteries do not last near as long as one would expect. As with any refurbed components your only running on borrowed time.

In the short term it MIGHT be a viable option to get you by for a year or so till you can budget in a new battery. But in the longterm i wouldnt advise such a thing to any customer of mine. From my experience dealing with refurb batteries its just throwing good money to the bad and shouldnt be done unless there is no other option.

Most battery companies will tell you otherwise but remember they are in the business to sell batteries(and/or service) and they will tell you anything you want to hear just to make a sale. Its what they dont tell you is what bites you in the end. Sure they can test cells and replentish electrolyte in them and deep draw and recharge and reseal them and make them look nice but in the end your still dealing with used material that does have a lifecycle inside these cells in these batteries. Once this lifecycle has reached its expected term no amount of reconditioning will ever bring it back to good usable condition for very long.
So once again i remind those that are not aware your only running on borrowed time when trying to save money by going the refurb way.

oh yes, from what i do remember about industrial battery warranties? they are usually 5 to 7 yrs depending on what type and size they are and this is for new batteries only, refurbed battery warranties vary usually from 30-90days to 1yr. This depends on the company doing the work.

On another note, a question to those that have dealt with battery companies and techs... if you pose the question to any number of battery techs about battery care and charging and maintenace how many different answers have you gotten on how this should be done? ponder this question next time you deal with a battery tech or salesman.

I'm sure your results will vary widely ;o)
